Specification of Letters Patent.

Application filed August 19, 1907. Serial No. 389,186.

Patented Dec. 15, 1908.

To all whom it may concern:

Be it known that I, LAWRENCE ZAMBONI, a citlzen of the United States, residing in New York, borough of Manhattan, county and State of New York, have made a new and useful Invention in Skate-Rollers, of which the following is a specification.

My invention has for its objects, first, to rovide a metallic skate roller havin two interlocking parts, provided with anges adapted to firmly secure or hold in place a yielding tire or tread. Second, to rovide a skate roller embracing two interloc ing metallic parts having flan es and an interlocking ring; together wit a yielding tire or tread Without a joint or integral throughout its mass. Third, to rovidemeans for more firmly securing a yie ding tire or tread on a skate roller than has heretofore been possible.

My invention will be fully understood by relflgriing to the accompanying drawings, in w c Figure 1 represents a cross sectional View" of my improved skate roller complete. Fig. 2 illustrates the manner of constructing my yieldin tire or tread without ajoint, so as to be in e ect integral throu hout its mass; and Fig. 3 represents a detaiI view showing my novel manner of holding or securing a leather or analogous tire at numerous points between the side retaining flanges of my skate roller.

Referring first to Fi 1, 1, 2 represent the opposite halves of a ro er or wheel provided with interlocking parts 4, 7 and outer side flanges 5, 6 having holding teeth 11, 11 stamped out and turned inward when the halves areformed; 3 being a split ring of strong steel wire or the like ada ted, when in position, to,hold the interlocke parts firmly together in the manner shown. 8 represents the hub secured between the central inner faces of the interlocking parts 1 and 2, and 9 represents a tire or tread made preferably of so being in effect inte al throughout its mass. The interlocking re ation of the parts 4 and 7 is such that it is continuous throughout and any pressure ut upon the outer surface of the part 7 wi tend to more firmly lock or hold the parts together, thus reventing any possibility of the rollen co apsing or the parts separating.

- In Flg. 2 I have illustrated the preferred" e leather constructed without a joint and manner of makin my novel tire or tread without a joint. prepare with male and female dies a cup having 'a bottom 10, the sidethereof being of the proper internal diameter, and constituting, when formed, the tire or tread 9. This is prepared by forcing a piece of solid fine grained sole leather through the dies under strong pressure, after which the bottom 10 is cut off in any preferred way; or, it may be cut out, if preferred, thus increasin the width of the tire. In fact a tube- 0 considerable length may be constructed in this manner and a number of the tires cut therefrom b lacin it on a maiid'rel and utilizing a Bathe an cutting too.

In assembling the parts the split ring 3 is first placed in position between the curved portions of the outer interlocking part. The tire 9 is then slippedover said interlocking part and the hub 8 is placed, one end in position against the inner face of the part 2. The part 1 is then forced into position with the part 4 inserted into the part 7, thuslocking all-of said parts securely together and causing the inwardl extending teeth 11, 11 at the outer edges 0 the flanges 5, 6, to pene-. trate the-lateral or side faces of the tire o'r' tread 9. In this manner I amenabled to securely bind the tire or tread 9 at every oint of its circumference directly to the two halves 1 and 2 of the roller, so that there is no possibility of any movement thereof. At the same time, the hub- 8 isheld in position between the two inner faces of the parts 1 and 2.

I have ascertained that a skate roller whenwearing effect on a rink floor. If preferred,

after the tire or tread is in position on the roller the outer face may be ,accurately turned off. a

.I'make no claim hereinafter to a wheel or roller having interlocking male and female parts in which the outer surface of one of the interlockin parts constitutes a art of the working be t or tread surface of t e wheel or roller, such feature constituting in part the subject'matter of a prior a plicationiiled by 105 me in the U. S. Patent 0 ce on the 6th day of March, 1905, bearing Serial No.'248,523.

Although my invention is specifically described.

lnwa y tion with a yie ding tlre or tread held in place between K said 1 teeth, substantially as designed for use as a skate roller, I do not limit the same for such purpose, as obviously it may be utilized in connection with casters for chairs, beds, sofas, and the like; or for 5 analogous purposes or uses generally.

Having thus described my invention what I claim and desire to secure by Letters Patent of the United States is- 1 1. A skate roller constructed of two me- 10 tallic disks having male and female inter.-

lockin parts located directly in the rim theme and provided with side flanges; in

combination with a' tire or tread held in place by said flanges, substantially as described. I

3.. A skate roller constructed of two me- 5 tallic disks having male and female interlocking lparts and side flan'es; in-co'mbination wit a tire or tread hel in lace b said flanges and a split ring adapte to ho d the locking interlocking stantially as escribed.

4'. A skate'roller constructed of two metallic disks having male. and female intertion wit a tire or tread hel in place b said flanges, a split ring adapted to hold t e interlocking parts firmly together, and a hub securel held in 5. Askate roller embracing two pressed metallic'disks curved outwardly'at or near their centers and provided with interlocking male and female. parts-which constitute a part of the rim, the outer edges of the rim ein provided with side flanges turned inwar y and havlng teeth; in combination with a yielding tire or tread held in place by said teeth; together witha hub secured between the outward curved central portions.

of the disks, substantiall as described.
